So, how about this? You make a video about you soloing Ragnarok Wind Disaster without Fire SSRs. I'm not saying you need to win. About halfway should be plenty of proof that you can carry your weight without those specific SSRs. If you get that far, you get to prove that "there's always workarounds, you just need to be a little smart" about teambuilding. Honestly, considering your grid, it should be plenty doable.
Meanwhile, I'll make a video about soloing Ragnarok Wind Disaster with a Water team. A debuff heavy Water team, since that's what Water does. I'm not expecting to win, but I get halfway through, that'd be plenty good for me. Considering how far my Water team is from the ideal one (zero of the Water holy trinity, but Ryu-Oh from an alternative build), if I get that far it should prove that on-element isn't the only option the game has.
Any objections? I need to sleep and head to work now, so I should be able to post a video of that in ~18 hours.
